How to avoid the breakage of the castable

The baking of refractory castables before use is an important part of the production process. Whether the baking system of the castables is reasonable or not determines the quality of the green body baking, which directly affects its performance, the manufacturer’s production process and Economic benefits. If the refractory castable is used carelessly, it will be damaged, so how to avoid it?

First of all, refractory castable is a widely used refractory insulation material, especially suitable for some places that need to be calcined at high temperature, but sometimes it may be damaged during use.

Castable

Different manufacturers of refractory castables have different formulas and compositions. The main components in refractory castables refer to the most common chemical components that have a decisive effect on the high-temperature properties of the castable. The refractory castables have excellent properties. The function of countering high temperature effect, and the characteristics of many refractory castables are all based on the main component and the additional component additives. At the same time, if the castables of some manufacturers have too much impurities, they will also cause damage and problems in future use. Therefore, the composition of refractory castables plays a decisive role in the high temperature properties of the castable. Only refractory castables with excellent composition materials can have excellent skills to counter high temperature effects, ensuring the effect and longevity of use.

In addition, physical factors are also important factors leading to the damage of refractory castables. Excessive temperature will cause local cracking of refractory castables. Irregular use of the kiln or mixing of liquid metal into the castable will also cause pouring. The material is damaged.

The second factor that causes damage to the refractory castable is chemical factors, because of the slag generation inside the furnace and the chemical reaction between the furnace gas and the refractory castable. In addition, the corrosive substances produced by electrochemistry will also cause local damage to the refractory castable. Therefore, the refractory castable should not be put together with strong corrosive substances during the construction process.

Then the refractory castable caused by mechanical construction is damaged by impact, so it is necessary to pay attention to it during use.
